Need Tech advice for hosting a local Rockband event

Hey guys, we’re going to host a Rockband event at a local youth cafe in a few weeks and I came here seeking for advice about it. We’re going to play Rockband 4 on PS5 on a projector. For audio we’ll be connecting the console with stationary speakers through the controller’s audio output. The problem is, that the HDMI cable from the projector is behind a bar at the other side of the room. That’s usually not a big deal when we host Mario Kart tournaments and connect the Switch but my drums and mic are wired and they’re not long enough to go from one side of the room to the other. My main concern now is if performance or latency would suffer from an additional HDMI cable as extension or if there are any cable lengths to avoid. Thanks in advance!
